Answer:

-2/3

Step-by-step explanation:

To find the slope of two points

m = (y2-y1)/ (x2-x1)

    = (-4-2)/(1--8)

   = (-4-2)/(1+8)

   = -6/9

   -2/3

Answer:

[tex]\large\boxed{\text{The slope}\ m=-\dfrac{2}{3}}[/tex]

Step-by-step explanation:

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-8, 2) and (1, -4). Substitute:

[tex]m=\dfrac{-4-2}{1-(-8)}=\dfrac{-6}{9}=-\dfrac{6}{9}=-\dfrac{6:3}{9:3}=-\dfrac{2}{3}[/tex]

Answer: 10 pounds of force

Answer:

10 lb of force are needed to lift the rock if the distance from the fulcrum is 6 feet.

Step-by-step explanation:

From the given graph it is clear the curve passing through the point (1.5,40), (2,30), (2.5,24), (3,20) and (4,15).

These points satisfy by the equation

[tex]y=\frac{60}{x}[/tex]

where, x is the distance in feet from the fulcrum and y is needed force in pounds.

Put x=6 in this equation,

[tex]y=\frac{60}{6}=10[/tex]

Therefore, 10 lb of force are needed to lift the rock if the distance from the fulcrum is 6 feet.

Answer:

D. Reciprocal parent function

Step-by-step explanation:

The given function has the x-axis as the horizontal asymptote

The vertical asymptote is the line x=0, which is the y-axis.

This means that the function has x, in the denominator.

Therefore, the function represented by the graph is [tex]\frac{1}{x}[/tex].

This is the parent reciprocal function.

The correct choice is D

Answer:

4b+7

Step-by-step explanation:

7 beads= +7

4 packs= 4b

expression= 4b+7

The solution to the question "write an expression to show the total of beads that lina uses" is:

The number of beads Lina has = 7

The number of beads in the four packets = 4n

The total number of beads that Lina now has = 4n  +  7

The number of beads Lina originally has = 7

The number of additional packets bought = 4

Let the number of beads in each packet be n

Total number of beads in the 4 packets = 4  x  (number of beads in each packet)

Total number of beads in the 4 packets = 4n

The total number of beads that Lina now has = (The number of beads in the 4 packets)  +  (The number of beads she originally has)

The total number of beads that Lina now has = 4n  +  7

Answer:

Mean: 116

Median: 115

Mode: 115

Step-by-step explanation:

Mean is the average of the data set; it’s found by adding up all the numbers and dividing that sum by the number of numbers there are

(114 + 120 + 115 + 114 + 118 + 117 + 114)/7 = 812/7 = 116

Median is found out by ordering the given numbers from largest to smallest and finding the middle number; if there are an even number of given numbers, you add them up and divide by two.

In this case, you are lucky enough to be given an odd numbers of given numbers

Ordering (smallest to largest):

114, 114, 114, 115, 117, 118, 120

Median is 115

(this is the number in the middle of the data set)

Mode is the most frequently occurring number in the data set

In this case, the

Mode is 114

The mean of the data is 116, the median is 115, and the mode is 114. All three measures offer insights into the dataset's central tendencies.

To find the mean, median, and mode of the given data: 114, 120, 115, 114, 118, 117, 114, let's follow these steps:

Mean: Add all the numbers together and divide by the number of data points.

Median: Arrange the numbers in ascending order and find the middle value. If there is an even number of observations, calculate the average of the two middle values.

Mode: The most frequently occurring value in the dataset.

Thus, the mean is 116, the median is 115, and the mode is 114.

Step-by-step explanation:

Answer:

x = 14

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 6, hence

sum = 180° × 4 = 720°

Each exterior angle plus it's interior angle = 180°

Subtract each exterior angle from 180 to obtain interior angle

180 - 80 = 100, 180 - 56 = 124, 180 - 61 = 119, 180 - 43 = 137, 180 - 92 = 88

The 6 th interior angle is the sum of the 5 interior angles subtracted from 720

6 th angle = 720° - (100 + 124 + 119 + 137 + 88)° = 720° - 568° = 152°

The 6 th angle and 2x sum to 180 ( same reason as given above )

2x + 152 = 180 ( subtract 152 from both sides )

2x = 28 ( divide both sides by 2 )

x = 14

Answer:

33

Step-by-step explanation:

Each holds 2.5*12 = 30 eggs.

1000/30 = 33.333333

So he fills 33 flats.

The number of flats he could fill is 33

Peterson needed to pack 1000 eggs into flats that held 2 1/2 dozen eggs. To find out how many flats he could fill, we need to calculate the total dozen eggs in 1000 and then divide by 2.5 dozen since each flat holds 2 1/2 dozen eggs.  One dozen equals 12 eggs. Therefore, 1000 eggs would be equivalent to 1000/12 = 83.33 dozen. To find the number of flats, we divide the total dozen eggs by the capacity of each flat in dozen: 83.33 dozen / 2.5 dozen = 33.33. This means Peterson can completely fill 33 flats, with a partial amount of eggs left over not sufficient to fill another flat completely.

Answer:

Step-by-step explanation:

The formula of a volume of a cone:

[tex]V=\dfrac{1}{3}\pi r^2H[/tex]

r - radius

H - height

We have r = 4 u and H = 6 u. Substitute:

[tex]V=\dfrac{1}{3}\pi(4^2)(6)=\dfrac{1}{3}\pi(16)(6)=\dfrac{1}{3}\pi(96)=32\pi\ u^3[/tex]

[tex]\pi\approx3.14\to V\approx(32)(3.14)=100.48\ u^3[/tex]

If the cylinder has the same radius and height as a cone, then the volume of the cylinder is three times larger than the volume of the cone.

Therefore, the volume of acylinder:

[tex]V\approx3(100.48)=301.44\ u^3[/tex]

Why?

The formula of a volume of a cone:

[tex]V_{cone}=\dfrac{1}{3}\pi r^2H[/tex]

The formula of a volume of a cylinder:

[tex]V_{cylinder}=\pi r^2H[/tex]

Therefore

[tex]V_{cone}=\dfrac{1}{3}V_{cylinder}\to V_{cylinder}=3V_{cone}[/tex]

If the radius and height are the same.

Answer:

A cone has a radius of 4 units and a height of 6 units.

Its volume is

[100.48]

cubic units. If a cylinder has the same radius and the same height as the cone, then its volume is

The value of a7 is 128

Step-by-step explanation:

* Lets revise the rule of the geometric series

-There is a constant ratio between each two consecutive numbers

- Ex:

# 5  ,  10  ,  20  ,  40  ,  80  ,  ………………………. (×2)

# 5000  ,  1000  ,  200  ,  40  ,  …………………………(÷5)  

* General term (nth term) of a Geometric series:

# a1 = a  ,  a2  = ar  ,  a3  = ar2  ,  a4 = ar3  ,  a5 = ar4

# an = ar^n-1, where a is the first term , r is the constant ratio

   between each two consecutive terms , and n is the position

   of the term in the series

* Now lets solve the problem

∵ a = 2

∵ r = -2

* To find a7 put n = 7

∵ an = a (r)^n - 1

∴ a7 = 2 (-2)^(7 - 1) = 2 (-2)^6

∵ (-2)^6 = 64 ⇒ even power canceled the negative sign

∴ a7 = 2 (64) = 128

Answer:

x = 1 + t and y = 2.5 + 0.75t

Step-by-step explanation:

Parametric equations are the equations in which the all the variables of the equation are written in terms of a single variable. For example in 2-D plane, the equation of the line is given by y=mx+c, there x is the independent variable, y is the dependent variable, m is the slope, and c is the y-intercept. The equation of the given line is -3x + 4y = 7. The goal is to convert the variables x and y in terms of a single variable t. First of all, take two points which lie on the line. By taking x=1, y comes out to be 2.5 and by taking x=0, y comes out to be 2.5. The general form of the straight line is given by:

(x, y) = (x0, y0) + t(x1-x0, y1-y0), where (x, y) is the general point, (x0, y0) is the fixed point, t is the parametric variable, and (x1-x0, y1-y0) is the slope.

Let (x0, y0) = (1, 2.5) and (x1, y1) = (0, 1.75). Substituting in the general equation gives:

(x, y) = (1, 2.5) + t(1, 0.75). This implies that x = 1 + t and y = 2.5 + 0.75t!!!

Answer:

x=t, y=(3/4)t+(7/4)

Step-by-step explanation:

We start by changing the equation the slope-intercept form.

4y=3x+7

y=(3/4)x+(7/4)

then we set x equal to t

x=t

and substitute

y=(3/4)t+(7/4)
